1971Sovereign bottom line

I have an old AS under the trees. I have always wanted to redo it. It is in bad shape, but mostly there and appliances work more or less. It will take axles and tires. I have a fair sized farm shop and can repair or fix many things. After reading many stories, I feel I have learned a great deal about the AS. My one question is, how much will the supplies cost to do a frame off refurb., plywood, paint, upholstery, rivets, pex, tambour, etc? I believe I have a handle on appliances, axles, tires. Yes, I can weld, sew, paint, rivet and repair appliances (and do surgery also). Just a guess is all I ask or in asking, does that mean just leave it under the trees? Thanks!
